What has been your best household buy in the last , say , 5 years? I have a new Gtech AirRam K9 cordless vacuum cleaner , it's amazing - lightweight , rechargeable , charge lasts about 20 mins , easy to push and empty , good on any floor covering , carpets etc . And no , I don't work for them! I bought it to keep and use upstairs , but it's so brilliant I'm going to get rid of my bulky upright Dyson , and use the AirRam up and downstairs . I also purchased the multi cleaner , also rechargeable this is very good too., for edges , spills and for use in the car .
